The DF96 is an amplifier pentode for use in battery portable radio equipment, mainly domestic broadcast receivers.

By 1954 the transistor was the next approaching technology and the valve industry responded with a range of 25 mA filament valves.

The plain anode and on the glass the words Made in England and BVA.

The filament can be seen as a single vertical strand. The tensioning spring is just visible at the top under the getter holder.

The thin glass tube envelope is 18 mm in diameter and, excluding the B7G base pins, is 47 mm tall.
